While many diet sites focus on how important it is to lose weight for appearance's sake, WebMd is quick to point out the slew of health problems that are a byproduct of obesity -- cancer, heart disease, gout, diabetes, arthritis, asthma and gum disease.

By changing your habits and following a program that includes good eating and exercise, you will make changes to your life that can be sustained for the long haul. In addition, you will improve your overall wellness. That is the goal of the WebMD Weight Loss Clinic.

Visitors perform a free assessment that discloses weight, height, age, sex and desired weight. Once they have paid the monthly $21.62 fee or $4.99 a week, they are then a member of the WebMD Weight Loss Clinic.

The next step is telling about food likes and dislikes so that WebMD can create a plan tailor made to your preferences. The program also examines your eating habits to determine where you need to make adjustments. Completing the questionnaire takes about 20 minutes, but the end justifies the means.
